III. Discourse Structure：(10%)     Some mosquito-borne diseases, say, malaria and dengue, had or have invadedthe U.S., both of which were brought from abroad by travelers. Now there’s a newinfectious invader to fear: Zika. 17 But at some recent point, perhaps during the2014 World Cup held in Brazil, an infected traveler brought the virus to LatinAmerica, where it spread to more than 20 countries and likely infecting hundreds ofthousands of people. 18 Since the first case of Zika in Brazil in May 2015, thecountry has reported some 4,000 cases of microcephaly – a severe birth defect. In2014 the country of 200 million reported just 150 cases of the abnormality. Scientists suspect that Zika infections in pregnancy may be causing microcephaly and possiblyforms of brain damage in infants. 19 To reduce the risks from Zika, desperategovernments in countries like El Salvador have gone so far as to urge women toavoid pregnancy until 2018.    So far, there have been a handful of Zika cases recorded in the U.S. The WorldHealth Organization has predicted that the disease will eventually reach everycountry in the Americas except Canada and Chile – the only two where the Aedesmosquito, which carries the virus, isn’t found. 20 There’s hardly a spot on theplanet, however remote it is, that’s more than 24 hours from a major city.     Signs show that the virus’ seemingly new ability to cross the placental barrierbetween mother and fetus suggests that it may have mutated, which presents anotherchallenge for scientists. Viral threats change and evolve, and so does the planet welive on. 21 They bite more and fly farther, and the viruses they carry tend toreplicate faster. So as public-health officials prepare for a new onslaught of insectbornedisease, a new reality is setting in: In a warmer, connected world, Zikabecomes a fact of life.
(A) The Centers for Disease Control and Prevention phpE9WUgz has warned pregnantwomen not to travel to affected countries in Latin America. 
(B) But the real worry is what the Zika virus seems to be doing to pregnant women. 
(C) Zika has been notorious for the catastrophic consequence coming with it. 
(D) First discovered in Uganda in 1947, Zika was an afterthought to disease experts. 
(E) The earth will be heating up, creating a better environment for mosquito-bornediseases to spread.(AB) Like other infectious disease that have threatened the U.S., Zika is a reminderof just how connected we’re all today. (AC) Humans may not like a warmer climate, but disease-carrying mosquitoes do.
